SELF=|NK|NG RUBBER STAMP.

SPECIFICATION forming part of Letters Patent No. 681,554, dated August 27', 1901. Application filed March 26, 1901. Serial No. 52,931. (No model.)

To all whom it may concern:

Be it known that I, ARTHUR EWART JAMIE- sON, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Self-Inking Rubber Stamp,of which the followingis a full, clear, and exact description.

My invention relates to rubber stamps of. the self-inking type, and has for its object to provide a very simple and efficient construction for this purpose which will produce a perfect impression.

The invention will be fully described hereinafter and the features of novelty pointed out in the-appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is afront elevation of myimproved stamp. Fig. 2 is a cross-section thereof; and Fig. 3 is a cross-section with the parts in a different position, the handle being omitted.

The stamp comprises an inverted- U-shaped frame A, to which is rigidly attached at the bottom the holder B for the stamp proper, O, which preferably is of the character known as an air-cushion stamp. To the top of the frame A is rigidly secured the handle D, provided with an axial bore D, through which extends a plunger-rod E, having at its upper end an operating-knob E. The lower end of the rod E is rigidly connected with a crossrod F, the ends of which are fitted to slide in vertical slots A of the side members of the frame A. These slots have lateral curved extensions A at their lower ends, and in said extensions, as well as in the lower portion of the slots A, is adapted to move a cross bar or rod G, secured to side members H of a U- shaped frame, the bottom member of which, H, carries an inking-pad I on its inner side. The rod G is located at a distance from the cross-bar F, to which the side members H of the pad-frame are pivoted. The side members H embrace the side members of the frame A, and in its normal position the pad I engages the type-surface of the stamp O, keeping it well supplied with ink and protecting it from dust. To hold the pad in this normal position, I connect with the bar F" springs J, having a tendency to pull it upward, the upper ends of said springs being received in sleeves A rising from the central member of the frame A. The springs are secured to screws K, working in nuts L, so that the tension of the springs may be ad justed as desired.

The normal position of the parts, as hereinbefore referred to,- is shown in Figs. 1 and 2. When it is desired to use the stamp, the handle D is grasped by the person, and the knob E is depressed with the thumb. This causes the pad-frame H H to swing into the position shown in full lines in Fig. 3 and in I dotted lines in Fig. 2, the guide-rod G following the curved extensions A of the slots A, while the cross-bar F has a purely vertical motion. Thus the stamp O is uncovered and may be pressed down upon the paper or other surface to produce the desired impression. When the knob E is released, the springs J will cause the parts to return to their original position.

The device is very simple and keeps the stamp in proper condition for a good impression.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the frame, the stamp carried thereby, the inking-pad, a cross rod or bar mounted to slide in the frame and to which the inking-pad is pivoted, a second cross rod or bar connected with the inkingpad and also mounted to slide in the said frame, and means for operating said pad to swing the same.

2. The combination of the frame, the stamp carried thereby, the swinging ink-pad having guided movement in said frame, a spring connected with the frame and with the ink ing-pad to normally hold the latter against the stamp, means for adjusting the tension of said spring, and actuating mechanism for swinging the pad away from the stamp.

3. The combination of the frame having vertical guideways with lateral extensions at the bottom, the stamp carried by the frame, the inking-pad adapted to lie against the stamp, superposed rods connected with said pad and mounted to slide in the guideways of the frame, and means for swinging the pad.

4. The combination of a frame having a handle provided with a longitudinal' bore, a stamp carried by the frame, a cross-rod mounted to slide in the frame, a frame carrying an inking-pad and having side members pivoted to the ends of the said cross-rod,

an operatin gp1unger connected with the said projecting upward from the frame, 'nnts at 15' the top of said sleeves, screws working in said nuts, springs connectedwith said screws and with a cross-bar connected with the inking-pad, and actuating means for swinging the pad against the tension of said springs. 20

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ARTHUR EWART JAMIESON.
